SERVICING
BRAKE FLUID
Keep the motorcycle upright and place the handle-
bars straight. Check the brake fluid level in both the
front and rear master cylinder reservoirs. If the fluid
level is below the lower level indicated in the figure,
add the correct type of brake fluid. Refer to the chart
below for the proper selection.

BRAKE AIR BLEEDING
Any air which may have been trapped in the brake
fluid circuit must be bled completely. If the brake lever
or brake pedal feels spongy or weak, then most likely
there is air in the hydraulic circuit. To bleed the air
from the front brake, use the following procedure.
Connect a clear hose to the air bleeder valve and run
the hose into a suitable clear container. Pour approx-
imately 1/2 in of brake fluid into the container so that
the end of the clear hose is submerged and cannot
draw any additional air back into the circuit during the
air bleeding servicing. Then close the valve, pump
and squeeze the lever, and open the valve while
squeezing brake lever.
Repeat this process until the fluid flowing into the
receptacle no longer contains air bubbles.
After bleeding the brake circuit, tighten the bleeder
valve to the specified torque. Replace the rubber pro-
tective cap. Be sure to check the brake fluid level in
the reservoir.
